Too bad, but this is because upstream Xen people didn't get their changes into the Linux kernel yet. Your options are to go back to something out of date and unsupported (Fedora 8 IIRC was the last version of Fedora that could be used as a Xen host). Or use KVM -- see above. Or use RHEL 5 or a derivative where an older version of Xen is fully supported.

Got Windows guests?
Hello fellow Fedora, libvirt and libguestfs users, If you have any Windows guests, then you can help Fedora to support Windows guests better by spending a few minutes testing the Windows Registry feature we just added to libguestfs 1.0.75. You will need: - A Windows NT/200x/XP/Vista/7/... guest - Fedora 12 or Fedora Rawhide host - libguestfs-tools >= 1.0.75 (from updates or http://koji.fedoraproject.org/koji/packageinfo?packageID=8391 ) - a few minutes of your time The tests: (1) Run the virt-win-reg commands shown in the following web page, where "MyWinGuest" should be replaced with the name of the Windows guest as known to libvirt: http://libguestfs.org/virt-win-reg.1.html#examples Do the commands run without any errors? Does the output look sensible? If you have several Windows guests, please try as many different sorts as possible! (2) Download the registry binary files and try to convert them to XML: guestfish -i MyWinGuest --ro <<'EOF' download win:\windows\system32\config\software software download win:\windows\system32\config\system system download win:\windows\system32\config\sam sam download win:\windows\system32\config\security security EOF hivexml software > software.xml hivexml system > system.xml hivexml sam > sam.xml hivexml security > security.xml Do those commands run without error? If there's an error, try adding the hivexml -k option. Does the XML look complete? (Try running the XML through tidy -xml -indent -quiet < foo.xml | less ) I hope you don't find any bugs, but if you do: Send a reply to this message, or report a bug in Bugzilla: https://bugzilla.redhat.com/enter_bug.cgi?component=libguestfs&product=Virtualization+Tools It's useful to include the following details: HIVEX_DEBUG=1 hivexml regfile 2>&1 > log.out The Registry file itself that is failing (but note that Registry files can contain sensitive data). It's also useful to have positive feedback ("it worked!"). Thanks for any testing you can give, and if you have any other suggestions for handling Windows guests from Fedora, please let me know.

There's no good solution. You will be able to run qemu, in software emulation mode. Depending on how fast your processor is, and how CPU intensive your Windows session is, it'll be either acceptably slow or very slow indeed.

You can't have a boot partition on LVM, _but_ you can share a single boot partition between [certainly Fedora, RHEL and CentOS] guests. You have to manually aggregate your grub.conf file, and make sure it is saved somewhere else between each install (because installs overwrite grub.conf), but other than there is no problem. In fact, if only there was a "grub.conf.d", you wouldn't even have to do that ... An idea for Anaconda perhaps ... You also have to make sure your /boot partition is large enough, given that it will be holding 6x its normal number of kernels. This is how I have set up several machines, and it works fine.

I do this - perhaps not gazillions, but 5 or 6 different versions of Linux + a Windows partition. /dev/sda1 Windows /dev/sda2 Shared Linux /boot /dev/sda3 Shared Linux swap /dev/sda4 Linux PV containing all Linux root fs's I use LVM for the Linux rootfs's, and I just have grub boot them directly.
